Claims

[Scope of utility model registration request]

A plurality of grooves and notches are provided on the outer surface of each of the fixed contact base of the electromagnetic contactor and the base frame of the coil, and a movable groove is provided in the base notch.
In a device that operates an auxiliary contact device by lowering the movable contact base by loosely fitting and protruding a protrusion provided around the probe base, the movable contact base is slidably fitted into the groove and abuts against the protrusion. The operation rod of the auxiliary contact device and a plurality of other auxiliary contact devices installed at a distance between the above-mentioned protrusion and the operation rod are installed, and the protrusion provided around the movable contact base is installed in the upper and lower directions. increase the thickness of
or an electromagnetic contactor characterized by being formed by reducing
